I noticed the following problem a few days ago & I can't think of any reason why it would have suddenly started.
When logging onto the domain with a domain controller (WINS server) I get the message - At least one service or driver failed to start during system startup. The system log is reporting Error 5721 - The setup session to the windows nt or windows 2000 domain controller <unknown> for the domain DOMAINNAME failed bacause the domain controller does not have an account for the computer COMPUTERNAME.
When I try to net view the main domain controller (by that I mean the 1st dc in the domain) I get a system error 5 - Access is Denied.
I have looked on the main domain controller and noticed there is no trace of the WINS server in DNS, AD Users & Computers or AD Sites & Services, it's as if it's vanished!!
I thought about removing the server from the domain using dcpromo, it goes as far as to try and remove AD then reports - The operation failed because : The specified domain either does not exist or could not be contacted.
I need this domain controller working as it previously has been, any help would be most appreciated. Thanks.
